" 2."9x^(2)+7x-2=0

In the following,determine whether the given quadratic equations have real roots and if so, find the roots 9x^(2)+7x-2=0 (ii) 2x^(2)+5sqrt(3)x+6=0

Use the remainder theorem to factorise the expression 2x^(3) + x^(2) + 7x-6 . Hence, solve the equation 2x^(3) + 9x^(2) + 7x-6=0

Solve the quadratic equation having real roots by quadratic formulae :(i)9x^(2)+7x-2=0 (ii) 6x^(2)+x-2=0

Show that the equation 9x^(2)+7x-2=0 has roots and solve it.

If x^(4) -5x^(3) + 9x^(2) - 7x + 2 = 0 has a multiple roots of order 3 then the roots are

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8

In the following, determine whether the given quadratic equations have real roots and if so, find the roots 9x^2+7x-2=0 (ii) 2x^2+5sqrt(3)x+6=0

If alpha,beta are roots of 7x^(2)+9x-2=0, find their position with respect to following (a)-3 (b) 0(c)1
